To all whom t may concern:

Be it known that we, EDWIN M. WHEE- Loori, residing at Minneapolis, in the county of Hennepin and State of Minnesota, EMERY F. WHEnLooK, residing at Northfield, inthe county of Rice and State of Minnesota, and DIoKINsoN O. WHEELOCK, residing at Minneapolis, in the county of Hennepin and State of Minnesota, citizens of the United States, have jointly invented certain new and luseful Improvements in Guide-Wheels for Plow-Motors, of which the following is a specification.l

Our invention relates to traction engines or motors used in plowing; and its object is to provide means for guiding the motor to cause it to travel along the side of a previously formed furrow. This object we accomplish by providing one of the steering wheels ofthe motor with a iiange, adapted to cont-act with the unplowed side vof the furrow. j n

Our improvements are illustrated in the accompanying drawings, in which- Figure 1 is a plan view fand Fig. 2 a side elevation of an engine or motor embodying our improvements; Figs. 3 and 4 are detail views of port-ions of the steering devices connected to the front axle; Fig. 5 is a sectional detail of a port-ion of a steering wheel and its guide-flange. j

We have selected for the purpose of illustration, and have shown in the drawings in somewhat diagrammatic form, an explosiveengine motor, which is the type of motor we prefer to use for plowing, but our improvements are adapted to be used in connection with motors of other types.

In the drawings 1 'designates the main frame of the motor, 2 the platform -for the operator, 3 the explosive engine, 4 thedriving-gear, 5 the rear wheels, 6 the front wheels, 7 the divided front axle, 8 the arms pivoted thereon, and 9 the equalizer for the pivoted members of the frontv axle, alll of which parts'may be of any usual or' suitable construction.

The axle 7 is preferably suspended from f the frame 1 by hangers 10,'which are stayed by braces 11. The bar 9 is arranged to be reciprocated transversely to the frame 1, and

it is provided with cogs 12, constituting a rack, ywhich is engaged by a pinion 13 1s operated by a steering-rod 14 that .1

rearward and is provided with a hand-wheel 15 in position to be turned by an operator on the platform 2. The axis ofthe pinion is journaled in a box 16 supported from the frame by a hanger 17; and a roller-bearing 18 for the bar 9 is supported by the hanger 17 below the pinion 13. The rod 14 is connected to the pinion axis by a universal joint 19. It will be apparent that by means of the devices described an operator can lreciprocate the bar 9 by turning the rod`14 so as to adjust the inclination of the front wheels'and thus steer the machine.

A gang of plows (not shown) may be connected to the motor frame in the customary way by chains 20, or rods, or other suitable means, to enable the motor to draw the gang for plowing.

To relieve the operator of the strain and labor of giving constant attention to the steering devices while plowing to cause the motor and plows to move in .proper direction with relation to the previously plowed ground, we provide one of the front wheels with a ange 21 ony the outer edge of its tread 22. The inner side of the iiange is prefer-v ably beveled, as showna't 23, and adapted tobear` against the land-side of the furrow to prevent the wheel from cutting into they land-side, and also to prevent .the motor from moving away from the furrow; and

the operator can, by setting the steering-gear in position to give the motor a slight tendency to move in that direction, obviate any tendency of the motor to move in the opposite direction, or toward the plowed ground. Such wheel flange is not only4 an aid to the operator in steering the4 machine, but in eect is made to serve as a positive and practically automatic guide for the machine while plowing along the side of a previously vformed furrow.

The flange may be formed integrally with or permanently attached to the, wheel,but it is preferable to have it detachable..- As illustrated, it is detachably secured by means of eye-bolts 24,',provided in the beveled ring or ange 21 and bolts 25 provided in the of the bolts 24.

, isy a plow motox` adapted to run on the surface and haying 4its inner side beveled for fric Having deseribed our'inven'tion, WhaJ we tional lengegenzxeni: with the land side of the claim and desire tosecure by Letters Paten@ furrow: substantially as4 set forth.
